SMOKE SEPARATOR Filed June, 14. 1928 ATTORNEYS Patented Aug. 11, 1931 UNITED STATES HARRY C. LYONS, OF MOUNT VERNON, NEW YORK SMOKE snran-a'ron Application filed June 14,

My invention relates to a method of, and apparatus for separating solid particles such as soot from the gaseous parts of smoke.

It is the principal object of the invention to provide an efiicient method of and apparatus for separating soot and the like from gaseous parts of smoke.

Other objects and features of invention will be apparent upon a reading of the specification taken in connection with the accompanying drawings.

Briefly stated, in the preferred form of the invention, I employ a shield or windbreaker to be positioned adjacent the current of smoke issuing from a chimney or the like to protect the smoke against side drafts. The smoke protected by said shield is caused to contact with means such as a water spray or an endless belt or both, for removing solid particles from the smoke. The soot or other solid particles may be collected after removal from the smoke.

In the drawings which show for illustrative purposes only, preferred forms of the invention Fig. 1 is a central vertical sectional view of an aparatus illustrative of the invention;

Fig. 2 is a similar view illustrating a slight modification.

In said drawings, 5 indicates conventionally a stack or chimney from the top of which smoke issues. A Windbreaker or shield 6 is positioned adjacent the current of smoke issuing from the chimney 5, and as shown in Fig. l the top may be closed as indicated at 7, so as to cause the smoke to pass downwardly and out beneath the bottom of the shield 6. This shield should always be efiective on the windward side of the chimney and may completely surround the chimney as shown more particularly in Fig. 1, so that no matter from which direction the wind blows, the smoke will be more or less shielded from side drafts.

Suitable means'may be provided for removing all or a major portion of the solid particles, such as soot from the smoke, and in the preferred form I employ a liquid spray which may issue from a pipe 8 extending about the chimney, and positioned at a 1928. Serial No. 285,243.

suitable location to cause the issuing current of smoke to pass through the spray. If desired, I may employ a pump 9 suitably driven as by a motor for forcing water or other liquid through the spray pipe 8. A filling pipe 10 may be provided for maintaining the body of liquid in the collector or sump tank 11 surrounding the chimney. v

lVith that form of the invention shown in Fig. 1, the smoke issuing from the chimney 5 is protected by the shield or Windbreaker 6, and is caused to travel downwardly and out beneath the lower edge of the shield 6. At any suitable point, for example, as shown in Fig. 1, a water or other spray is positioned in the path of the smoke and solid particles such as soot and the like are collected by the water spray and either dropped down into the collector tank 11, orcollect on the inner side of the shield 6, and then run down with the spray water into the tank 11. When a pump such as 9 is employed, the liquid may be used over again to collect thesoot or other solid particles. From time to time, the solid matter may be removed from the sump tank 11, and the supply of water in the tank may be replenished as required through the filling pipe 10.

In the form shown in Fig. 2, I employ a Windbreaker or shield 6 which may be, and preferably is open at the top. The smoke issuing from the chimney 5 and protected by the shield 6 is caused to contact at some suit; able point such as above the shield 6, with means such as an endless belt 15 which may be caused to travel past the upper end of the shield. The belt 15 may be positioned any suitable distance above the shield 6 soas to permit the passage of all or a substantial quantity of the smoke issuing from the chimney bet-ween the belt 15 and the upper edge of the shield 6. If desired, the endless belt 15 may be positioned very close to and sub-Y stantially form a top closure for the shield 6, thus necessitating the final exit of the smoke through the lower end of the shield. Means such as a scraper 16 may be employed for removing collected soot from the belt 15. If desired, the belt 15 may be moistened by any suitable means such as the liquid spray issuing from a pipe 17 The soot removed by the scraper 16 may fall into a collector tank 18 which may be partly filled with water to better retain the solid particles.

In addition to the soot collector 15 positioned in the current of smoke protected by the shield 6 I may employ the spray pipe 8 and other mechanism heretofore described in connection with Fig. 1, and as illustrated in elevation in Fig. 2. I

It will thus be seen that by means of my improved method and apparatus, all or a major portion of the soot and other solid particles usually contained in smoke may be removed from the smoke before it is finally discharged into the atmosphere. Thus the air will not be polluted with soot and other solid Particles.

While the invention has been described in considerable detail I do not wish to be strictly limited to the forms of apparatus herein demrib'ed, since many changes may be made within the scope of the invention as defined in the appended claims.

1. In a smoke separator, a shield to protect the current of smoke issuing from a chimney or the like against side winds, means to collect solid particles from the smoke protected by said shield, and multip'erforated spray means surrounding the exterior of said chimney below the top thereof for spraying a lipid into the current of smoke to separate urther solid matter from the gaseous portion of the smoke.

2. In a smoke separator, a shield to protect a current of smoke issuing from a chimne 'or the like a' ainst side winds; said shield being jclosed at the top thereof by an endless belt for collecting solid particles in the smoke, and means for moistening said belt.

3. In a smoke separator, a shield to protect a current of smoke issuing from the chimney or the like against side winds, means to collect solid particles from the smoke protected by said shield, scraper means for removing solid particles from said means, and means for spraying a liquid into the current of smoke to separate further solid matter from the gaseous portion of the smoke.

v 4:. In a smoke separator, a shield closed at the to and sides and open at the bottom thereo to protect a current of smoke issuing from a chimney or the like against side winds, means to collect solid particles from the smoke protected by said shield, and means for spraying a liquid into the current of smoke to separate further solid matter from the gaseous portion of the smoke.
